HC2VPP-232 - Secondary table lookup support

Ietf models now contains case table-lookup to be able to define
lookup to secondary table. It must be separated to dedicated case
as combining secondary-vrf and other next hop types(simple,multi,special)
does not make sense, its either you define lookup to table,
or you specify next hop of some kind.

This patch works properly only for write,
as read is affected by VPP-994/VPP-995.
Read at this state can detect that route is using table lookup,
but can't detect table that is used for that lookup.

Also, HC2VPP-237 must be done in future
